SHOE-BLACKINGt STAND.

To all whom it may concern Be it known that I, WALTER T. MAHIN, acitizen of the United States of America, and resident of Harrisburg, inthe county of Dauphin and State of Pennsylvania, have invented certainnew and useful Improvements in Shoe-Blacking Stands, of which thefollowing is a specification.

This invention relates to shoe blacking stands and has for its objectthe provision of novel means for retaining a shoe in position to beshined, the said means comprising clamping members adapted to partiallyembrace the edges of the sole of the shoe under the instep in order thatthere will be no obstruction to the free movement of the implement usedin cleaning and shining the shoes.

A further object of this invention is to provide novel means foroperating pairs of clamps which are designed to engage the sole atdifferent points longitudinally of the sole, thus preventing lateralmovement of the shoe or any twisting of the shoe with relation to thesupport, a further object of the invention residing in the provision ofmeans for operating the pairs of clamping members in unison andpermitting the equalization of the pressure or clamping action of eachpair, notwithstanding that they are operated from a single lever.

WVith the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this specification wherein likecharacters denote corresponding parts in the several views, and inwhich- Figure 1 illustrates a view in perspective showing a standembodying the invention; Fig. 2 illustrates a view in side elevation ofthe upper portion of the said stand; Fig. 3 illustrates a top plan view;Fig. 4 illustrates an enlarged detail plan view underneath the footsupport, the means for connecting the foot support to the standard beingshown in section; Fig. 5 illustrates a view of the parts shown in Fig. 4in a different position of adjustment; and Fig. 6 illustrates a verticalsectional view of the foot support and the clamp operating Specificationof Letters Patent.

mechanism, looking from the front, the lever being partly in section.

In these drawings 7 denotes a base plate, 8 a standard, and 9 acompanion standard. The standards 8 and 9 have their lower ends bent atangles to form the feet 10 and 11 respectively which are secured to thebase 7 by the fastenings 12, which may be of any appropriate type. Thestandards 8 and 9 are separated at the base but converge and haveparallel portions 13 and 1 1 respectively in contact and securedtogether by the fastening 15. The standard 9 has an extension 16 whichis connected to the plate 17 forming the foot support whereas thestandard 8 has its upper end supporting a yoke 18 provided withangularly disposed ends 19 secured to the plate 17 by devices 20 whichmay be in the form of rivets or other appropriate means. The extension16 of the standard 9 is provided with a bolt 21 by which it is connectedto the plate 17.

The slotted bar 22 is supported under the plate 17 in spaced relationtherewith. the said slotted bar being held by the bolt 21 and by a rivetor like fastening device 23 by which it is held rigid with relation tothe plate 17. The slotted member 22 is here shown as having two slots 2%and 25, each of which extends longitudinally of the said bar and theslots are provided for the purpose of permitting movement of the pins 26and 27 to which the clamps are connected, it being observed that the pin26 is confined in the slot 2 1 and the pin 27 travels in the slot 25.

The pairs of clamps consist of the clamping members 28 for one pair ofthe clamps and the clamping members 29 for another pair of clamps. Theclamping members are similar if not identical in construction, eachconstituting a curved plate, the clamping members 28 havinglongitudinally extending slots 30 and the members 29 having similarslots 31. The clamping members of each pair are oppositely curved asshown in the drawing and are pivoted on the pins 26 and 27. Guiding lugs32 are provided for the clamps 29, the said lugs extending from theunder surface of the plate 17 through the slots 30 and 31 respectively,so that the clamping members are guided by the lugs, and owing to thecurved formation of the clamping members and the curved slots therein,the clamping members are actuated laterally of the plate 17 when themeans for actuating the clamping members (to be presently explained) isoperated. Each clamping member 28 has a lug 34 and each clamping member29 has a lug 35, the said lugs 34 and 35 being preferably slightlycurved to partially embrace the edge of the sole of a shoe so as toprevent vertical move ment of the shoe when the clamps are op erated tohold the same.

As a means for actuating the clamps in the manner heretofore stated, toproduce an equalization of the pressure of each pair of clamps, the pin26 has a link 36 connected to it and the pin 27 has a link 37 connectedto it. The ends of the links remote from the clamps are pivoted toopposite ends of a rocking bar 38 by the pins 39 and 40 re spectively itbeing shown in Fig. 1 that the end of the rocking bar 38 is providedwith a slot 41 for the reception of the link, it being understood thatthe opposite end of the said rocking bar is likewise provided with aslot (not shown) for the reception of the opposite link.

The rocking bar is rockably mounted at its longitudinal center in alever 42 which lever terminates in a head 43, the edge or periphery ofwhich is provided with notches forming the teeth 44 adapted to beengaged by a detent, to be presently explained, whereby the lever isheld in different positions of adjustment. Brackets 45 depend from thelower surface of the plate 17 and each has an aperture 46 for the pivot47 on which the lever 42 is mounted so that by swinging the lever 42 onits pivot, the links 36 and 37 which are connected to the rock bar 38are reciprocated, thus communicating motion to the clamping members andoperating them in the manner stated.

The fastener 23 which holds the slotted bar 22, serves as an anchor fora rod 47 which extends forwardly from its point of anchorage and intoand through the head of the detent 48 which engages the teeth on thehead 43 of the lever for holding the lever at different positions ofadjustment. There is a spring 49 encircling the rod 47 interposedbetween the detent head and the end of the slotted bar 22, the saidspring being operative to force the detent into engagement with theratchet teeth. The detent 48 is formed integral with a plate 50, thesaid plate being guided between the brackets 45 and having a slot 51therein for the reception of a screw 52 provided as a further means forguiding the said plate. The end of the plate remote from the ratchet isbent at an angle to form a lug 53 which may be pressed by the operatoragainst the action of the spring 49 for disengaging the detent from theteeth.

It will be apparent that an operator, may, when the clamps are in theposition shown in Fig. 4, pull the lever to cause the clamps to movetoward the positions which they are shown to assume in Fig. 5, and thesaid clamps will travel to such a distance as will cause them to engagethe edges of the sole of the shoe which occupy the upper surfaces of theplate, it being understood that regard less of the action of one pair ofclamps, the other pair will be caused to engage the sole of the shoewith pressure equal to that of the other pair. hen the lever has beenoperated to produce the required action of the clamps, it is held inposition to which it is drawn by the detent or ratchet, and when it isnecessary or desirable to release the shoe which has heretofore beenclamped, pressure on the outer end of the plate 50 will result indisengaging the detent from the ratchet teeth, permitting the retractionof the lever and the release of the clamps. The relation of the lever tothe means for operating the detent is such that both may be convenientlymanipulated by one hand.

Owing to the fact that the plate for supporting the shoe is withoutmeans for supporting the heel of the shoe, the said heel extends downpast the end of the plate and is adapted to bear against the end of theplate so that the edge of the sole is in position to be clamped by theclamping members. A plate of this character, which permits the heel toextend below the surface of the plate insures proper stretching of theleather or shoe material so that the surface may be evenly treated. Itis well known that where the heel is supported on the plane of the sole,the shoes crease above the heel and interfere with effective polishing.Furthermore, the fact that the clamps engage the sole under the instepprovides for the clamping of soles of different widths and owing to thefact that at this point the soles of all shoes are practically uniformone set of clamps will answer for any of the different shoes.

I claim- 1. In a blacking stand, a support, a plate attached thereto, aslotted bar secured in the plate and spaced therefrom, oppositely curvedclamping members forming pairs of clamps, said clamping members havinglongitudinally disposed slots, pivots connecting the inner ends of eachpair of clamps each of the pivots being slidable in a slotted portion ofthe slotted bar, guiding lugs carried by the plate and extending intothe slots of the clamps, links connected to the pivots of the clamps, arocking bar to the opposite ends of which the links are connected, apivotally mounted lever in which the rocking bar is rockably mounted,and means for holding the lever in different positions of adjustment.

2. In a blacking stand, a plate, a support therefor, a slotted barsupported by the plate and spaced therefrom, oppositely curved clampingmembers arranged in pairs and provided With slots, lugs depending fromthe under surface of the plate and extending through the slots of theclamping members, pivots slidable in the slotted bar on which the pairsof clamping members are mounted, links connected to the pivots, a rockbar, a lever in Which the rocking bar is oscillatingly mounted and toWhich the opposite ends of the links are pivoted, teeth formed on aportion of the lever, a detent for holding the lever in diflerentpositions of adjustnient, a guiding bar extending longitudinally of theplate, said detent having an aperture to receive the guiding bar, and aspring interposed between the detent and the guiding bar for holding thedetent in engagement with the teeth of the lever.

In testimony whereof, I hereunto aflix my signature in the presence oftwo Witnesses.
